Description:Two mortar bombs struck a square filled with Shi'ite Muslim pilgrims in Iraq's capital Baghdad on Sunday (June 10), killing at least six people and wounding 38, police and hospital sources said. Although overall violence in Iraq has dropped, Sunni Islamist insurgents with links to al Qaeda are still capable of lethal attacks and hit Shi'ite targets to stir up the kind of sectarian pressure that almost led to civil war in 2006-2007.(0:41)
